IMPROVEMENT IN SAP-SPOUTS.

Specification forming part of Letters Patent No. 117,457, dated July 25, 1871.

To all whom it may concern:

Be it known that I, OHARLEs (J. PosT, of Hinesburg, in the county of Ghittenden and State of Vermont, have invented certain new and useful Improvements in Metallic Sap-Spouts, and the mode of securing them to the tree and also securing the bucket-hanger in a proper position; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which Figure 1 represents an isometrical. side view of one style of my improved metallic galvanized sap-spout, with a detachable buckethanger on the place for securing it in a proper position. Fig. 2 shows a top view of the same spout without the bucket-hanger. Fig. 3 shows a slightlymodified form of the spout and bucket-hanger, to allow the sap to flow over the top as well as through the orifice in the stem. Fig. 4 shows a top view of Fig. 3 without the bucket-hanger.

My invention relates to metallic sap-spouts, and is an improvement on my original Eureka sap-spouts, patented to me November 24, 1868.

The flange or shoulder 61-, as seen in Figs. 1 and 2, is made conical or beveling, so that when the stem A is driven into the tap or bore of the tree it will close the orifice around it air and water-tight, so as to prevent any leakage of the sap, and also the air from drying up the pores of the wood near the bark to check the flow. Underneath the stem A is a small orifice, f, to admit the flow of sap through the partition or flange d (which forms the shoulder and packing) into the pod of the spout B. In Figs. 8 and 4 a small notch or opening, j, is shown, made in the top of the spout, in the portion of the stem or bevel d that just enters the bore in the tree, so that the sap can flow over into the spout B and keep the hole or tap full to prevent the air from entering the bore to dry it up. In spouts so constructed the orifice f may be dispensed with, if desired. The bucket-hangers are made of wire, and are very similar to those in use on my Eureka sap-spout.

Havingthus described my improvements, what I claim as my invention, and desire to secure by Letters Patent, is-- A notch or opening, j, on the top of the stemflange d for the sap to flow over into the spout B, so that the tap or bore will be kept full and moist, as herein described.
